  • PURPOSE: In this study, we tried to find out what kind of exercise was more effective in sleep disorder by comparing melatonin in blood after applying low intensity with high intensity exercise to sleep disordered rats induced by experiment. METHODS: We used male Sprague-Dawley rats which were 8weeks old and weighted 300g. They were supplied with water and food without any restriction. We kept the room temperature at $25^{\circ}C$ and controld the length of day and night in 12 hours blocks, respectively. We divided the rats 60 into 2 groups. To one group we applied low intensity exercise, and to the other we applied high intensity exercise for 15minutes per day over a period of 4 weeks. We extracted the blood from abdominal aorta before, after exercise, moved into EDTA tube, performed centrifugation. We decanted the serum $200{\mu}l$ from the blood into microcentrifuge tube by samples and moved into polypropylene culture tubes with micro pipette. We split enzyme solution $50{\mu}l$ into the tubes with melatonin direct kits and make them react at $37^{\circ}C$ for 2 hours. We split assay buffer $50{\mu}l$ into each tube and mixed melatonin tracer $50{\mu}l$ and melatonin antiserum $50{\mu}l$, respectively. After we made them react in room temperature, we decanted the superficial layer with a centrifuge and measured the activity for 1 minute by competitive method with ${\gamma}$-counter equipment. We draw a standard curve through logit-log graph with CPM(counts per minute) and counted the melatonin by B/B0. We conducted independent t-test to examine the homogeneous of melatonin value of before low-intensity and high-intensity exercise. We performed paired t-test to compare before and after low-intensity and high-intensity exercise, respectively. We carried out independent t-test to compare melatonin value after low-intensity and high-intensity exercise. Significance level was .05. RESULTS: The results were as follows; firstly melatonin was more increased in the group who was exposed to high intensity exercise when we compared before to after high and low intensity exercise, respectively. Secondly, high intensity exercise was more effective than low intensity exercise when we compared the two. CONCLUSION: In conclusion, secretion of melatonin which is the material of sleep improvement could be promoted by high intensity exercise. Low intensity exercise acted as a stress rather than improving sleep and had a negative effect on the secretion of melatonin because the melatonin was affected by stress.

  • The purpose of this study is to investigate risk factor found in the patients with stroke in physical therapy. A questionnaire survey was carried out for 130 the patients, who had comparatively alert mentality, hospitalized in kyung hee oriental medical hospital with stroke from January, 1st to May 31st, 1996. Major findings of this stuty were as follows. 1. The stroke patients 67(51.5%)were males and 63(48.5%) femals. The age groups of 50 to 69 years accounted for 67.6% of the total stroke patients are the highest. The job groups of commerce and business of patients 58.5%. The living groups of major citys of the revealed the highest incidence(40.8%). 2. There were 40 patients (30.8 %) who had hemorrhage related condions as the direct cause of their stroke, and 90 patients (69.2 %) who had cerebral infarction with no hemorrhaging as the cause. of the disease that the patients suffered from before their stroke, blood pressure related problems were most numberous 76 patients(58.5%) had such problems. 3. A month before their attack of stroke, were asked what thay thought could become the causes of their strokes. The most frequently mentioned answers were fatigue, drinking too much, and smoking, as chosen by 45 patients(34.6 %). 4. In regarding the relation between stress and stroke, (37.7%), of the surveyed belonged to the most numerous group had of people who said they were not under stress. Yet this group had a large number of parents. And 22.3 % of the surveyed named conflicts among parents, siblings, and relatives. 5. Questions were asked to find out the relationship between complications of stroke and smoking or drinking. It was surprising to see a high rate of attack among the 55.4 % majority who answered that they did not smoke nor drink. 6. To sum up the affect of food on attack of stroke, 42.5% of the people who had a sprcey and salty diet had a higher rate of attack then the group of people with leisurely nature. 7. Looking at the family history, 40.4% of the patients said their parents also suffered the disease. This percentage is the highest. And 40.0% answered that there is no one who suffered in their family history. Judging from the percentages and family.

  • 폴리프로필렌(PP)은 고결정성 범용수지로서 염색성, 내열성, 촉감 등의 문제로 의류용 소재로는 부적합하여 초기에는 카펫용 섬유로서 가염형 폴리프로필렌 섬유가 상업화 되었지만 성공하지는 못하였다. 그 후, 섬유 산업도 의류용 외의 산업자재, 생활 자재 분야 등이 성장함에 따라, 폴리프로필렌 섬유의 수요가 확대되었다. 최근들어 스포츠 액티브 의류가 일반의류 트렌드로 들어오면서 기능성 섬유가 요구되고 이 분위기에 맞춰 다시 한번 폴리프로필렌 섬유의 의류화가 요구되는 시점이 되었으며 섬유중 에너지 소비량이 가장 적고, 쉽게 재용해할 수 있으며 소각시 유해 가스발생량이 매우 적은 특징등이 있기 때문에 지구 환경보호의 입장에서 폴리프로필렌 섬유가 재검토되고 있다. 이번 실험은 분산염료를 이용하여 농도별, 온도별, 시간별, 후처리시 시간과 온도의 변화로 가염 PP/PET 섬유의 염색특성을 알아보기 위해 실험 진행하였다. 실험에 사용되는 시약은 1급으로, $CH_3COOH$, NaOH, $Na_2S_2O_4$이며, 조제는 분산제, 정련제를 사용하였다. 먼저 온도별 실험에서 $40^{\circ}C$에서 승온하여 각각 $100^{\circ}C$, $110^{\circ}C$, $120^{\circ}C$, $130^{\circ}C$에서 온도에 따라 염색되는 정도를 알아보았다. 가장 높은 흡진을 보이는 온도에서 각각 40min, 50min, 60min, 70min 염색 유지시간 실험을 하여 염색이 안정되는 시간을 측정하였다. 위의 실험 결과 최적의 조건으로 염색농도에 따른 Build up 실험을 진행하였다. 가염 PP/PET 섬유는 일반 Polyester처럼 $120{\sim}130^{\circ}C$에서 가장 높은 염색농도 값(K/S)을 보인다. 또한 $130^{\circ}C$에서의 유지시간에서는 50 min 이상 진행시 더 이상의 흡진이 없거나, 염료의 탈락이 있음을 알수 있다. Build up 실험에서는 8.0%까지 실험하였지만, 결과는 그 이상농도를 사용하여도 염색은 가능함을 알 수 있었다. 후처리에 대한 실험에서 염료에 따라 차이가 있지만 크게 영향을 받지 않는 것으로 보이며, 제품성 평가 결과를 보면 후처리를 했을 경우 견뢰도가 우수한 것을 알 수 있었다.

  • Objectives : The purpose of this study was to verify the impact of the empowerment of dental personnels as one of variables affecting the performance of dental institutions and to seek ways of boosting their organizational productivity. Methods : The subjects in this study were dental personnels who worked in dental institutions. After three investigators were trained, a pilot survey was conducted from October 20 to November 20, 2009, and the questionnaire used in the pilot survey was finalized. The collected data were analyzed with a SPSS(Statistical Package for the Social Science) WIN 12.0 program. The findings of the study were as follows: Results: 1. The dental personnels investigated got 3.98 in meaningfulness, one of the empowerment factors. They found a meaning in their job when they performed it. 2. The dental personnels who were older were more excellent in self- determination and influence, and age made a significant difference to their empowerment. 3. The dental personnels who were better educated were more superior in terms of empowerment, and academic credential made a significant difference to their empowerment factors was statistically. 4. The dental personnels whose yearly salary was larger were more which were the factors of empowerment of each factor was statistically significant. 5. Dental health agency workers less than three years accounted for most of 152 people were working longer duration of empowerment as a whole was that each of the factor scores. Empowerment of each factor was statistically significant. 6. The dental hygienists made up the largest group among the dental institution employees, and the kind of occupation made a significant difference to meaningfulness, competency and influence, which were the factors of empowerment. 7. The greatest group of the dental personnels worked in dental clinics, and the dental hospital employees surpassed the dental clinic employees in competency, self-determination and influence. There was a significant difference in the influence factor according to the type of dental institutions. Conclusions : Thus, the dental personnels were more aware of the meaningfulness factor when their perception of the job-related empowerment was checked, and it indicated that most of them attached importance to meaningfulness during their job performance. But just employees who worked in dental institutions located in particular regions were examined, the findings might not be generalizable. In the future, more extensive research should be implemented, and the sorts of programs that could stir up empowerment among dental institution employees or bolster organizational empowerment should be developed.

  • The aim of this study was to develope a fishing technology for fisheries management for improving the survival rate of young fishes escaped from trawl net. Sea experiments were carried out to investigate the survival rate of the fishes in off Geomun island and Korean southern sea. Cover-net fish cage was designed and manufactured to collect fishes escaped from COD(codend) and TED(trawl escapement device). Fish cage was installed in a shallow site where scuba diver can observe the surviving fishes after separating the cage from trawl net. Most of fishes except horse mackerel(Trachurus japonicus) and mackerel(Scomber japonicus) could escaped through TED(bar space 35mm) easier than COD(mesh size 54mm). Especially, escapement rate of redlip croaker(Pseudosciaena polyactis) escaped from TED was the highest as 73.9%. Survival rate of horse mackerel(Trachurus japonicus) escaped from TED was 85.5% at the point of 96 hours over, while the survival rate for COD showed a rapid decrease according to the time elapse as 85.0% at the point of 24 hours, 76.4% for 48 hours, 62.7% for 72 hours and 56.1% for 96 hours. Over 90% of red seabream(Pagrus major) and rock bream(Oplegnathus fasciatus) escaped from TED were survived 96 hours over and the survival rate of those fishes were excellent compared with the other fish species. All korean pomfret(Pampus echinogaster) escaped from both COD and TED were died within 48 hours. Most of redlip croaker(Pseudosciaena polyactis) were also died within 12 hours because of the weak physiological characteristics by water pressure change. Survival rate of fishes like as horse mackerel(Trachurus japonicus) having hard skin was high while it was low for the fishes like as squid(Todarodes pacificus) and hair-tail(Trichiurus lepturus) having soft skin. We could know that there were big differences in the survival rate offish species escaped from trawl net.

  • Objectives The purpose of this study is to find the relationships between the allergy and weakness in children in Seong-Dong district. Methods 802 day care centers children were participated for survey on allergic disease, risk factors, and weakness. From the result, we analyzed the relationships between the aforementioned factors. Results 1. 802 children were participated for the survey. We eliminated survey answers with unclear answers, and selected 792 survey sheets as our final subject of study. The age of majority of subjects(720 children) were between one to six years old, and the others were under the age of one and over seven. 2. The prevalence rate of asthma in a lifetime was 6.69%, allergic rhinitis was 14.87%, atopic dermatitis was 28.82%, allergic conjunctivitis was 6.29%, food allergies was 9.58%, and drug allergies was 1.4%. In 2009, the prevalence rate of allergies during treatments is 6.69% for asthma, 13.41% for allergic rhinitis, 13.64% for atopic dermatitis, 4.13% for allergic conjunctivitis, 5.23% for food allergies, 0.96% for drug allergies. 3. The significant risk factors were types of dwelling, pet with fur, dirty environments without vacuum cleaners, the numbers of times bed covers were washed, frequency of air ventilation, changes in body after moving, family history. 4. The distribution of the number of children with weakness within the five visceras were respiratory weakness, digestive weakness, psychoneurologic weakness, neuromotor weakness, and urogenital weakness in the order of most to the least. More specifically, children who only has respiratory weakness were the majority, while children who have respiratory and digestive weaknesses, children who have respiratory, digestive, and psychoneurologic weaknesses, children who have respiratory and psychoneurologic were followed. 5. With the exception of children with urogenital weakness, Most of the children with respiratory weakness, digestive weakness, psychoneurologic weakness, and neuromotor weakness had been treated for allergies in 2009, while children who were diagnosed with allergic diseases at least once in their lifetime most likely had weak respiratory, digestive or psychoneurologic systems. Conclusions The results of this study showed that there was a correlation between children with weak viscera and children with allergic diseases. However, further research would be necessary.
